3 Claims.

My invention relates to windows, more particularly to storm windows, andconsists in improvements in structure, by virtue of which it becomesfeasible and advantageous to construct such windows of metal,particularly aluminum.

My window structure consist essentially in a frame that includes one ormore window sashes in removable assembly. In accordance with the objectsof the invention I provide a metal storm window that is more efiectivein service, that is of economical and simple construction, that permitsthe assembled window structure to be readily and quickly installed inservice position and removed, and that permits the sashes of theassembly to be readily removed from, and returned to, weather-tightassembly with the frame.

In the accompanying drawing:

Fig. I is a view in elevation of a window structure embodying theinvention;

Fig. II is a, fragmentary sectional view, showing the structure tolarger scale, partly in elevation and partly in section on the planeII--II, Fig. I;

Fig. III is a view comparable with Fig. II, with the qualification thatcertain elements of the window structure are shown removed from theframe;

Fig. IV is a fragmentary'view, showing the two sashes of the structurein edge elevation, as seen on the plane IVIV of Fig. I;

And Fig. V is a fragmentary view of the assembled structure, comparablewith Fig. I. Whereas Fig. I shows certain locking elements of thestructure in sash-securing position, Fig.

V shows them in release position.

The window structure of this invention is primarily designed to serve asa storm window, and I shall describe the structure as it is-so used,

with the understanding that certain features of.

its construction will prove valuable in windows generally, whatever bethe particular association or organization in which it is used.

The window structure consists in a rectangular frame I, including arectangular opening 2,

nately, the frame plate I may be permanently installed in the windowcasing, and the sashes 3 and 4 removed during the warm seasons, and,

if desired, a panel of fly screen installed in place of the sashes. v r

The plate-like frame or frame plate l is formed in proper size to fitthe particular window casing, and it is provided with marginalperforations 5, for the reception of screw nails, orother devices, forremovably securing the frame within or upon such casing, in spacedrelation with respectto the window sashes permanently installed therein.V

In Figs. I and V, the assembled. storm window is shown. from the inside,that is, from the side that faces the panes of the permanent windowstructure. The plate-like body of the frame includes adjacent to its.lower edge one or more sets of weep-holes 6 by means of which condensatemay escape from therspace between, the storm window and the permanentwindowsashes. The weep-holes also serve to admit of such slight aircirculation as is effective to prevent the glass panes of the assemblyfrom sweating. Conveniently, flaps 60 are arranged to cover thevweep-holes when desired.

-.in weather-tight assembly in the frame I, yet

are readily removable from the frame at will. Handles I are provided onthe sashes, to facilitate manipulation.

As shown in the drawing the sashes are essentially plate-like structuresthat are smaller than the frame plate I and are adapted marginally tooverlap the inner margin of the frame plate, and to rest in face-to-faceabutment thereon. The sash plates include circumferential pane-receivingflanges 3a (Figs. II and III) that in the as sembly extend outwardlythrough the opening 2 in the frame plate I. In assembly, the two sashesmeet edge to edge on the horizontal cen-, ter line of the opening 2 inthe frame, and it will be noted that the two sashes extend in commonplane, engaging each other at their meeting edges in a rib-and-grooveunion 8 '(FigIV). The rib is formed integrally on the top edge of thelower sash, and the groove is formed in the lower edge of the uppersash; the union is water-tight; indeed, I may provide a felt lining (notshown) on the walls of the groove, so that the union will besubstantially hermetic.

Considering the structure in greater detail, the frame I includes twoflanges 9 and Ill that ex-' tend peripherally of the rectangular opening2 in the frame I. These two flanges extend in parallelism and inuninterrupted continuity around the opening 2; and they arespaced-apart, as viewed in cross section (Figs. II and III), the flange9 lying in this case in common plane with, and comprising an integralportion of, the plate-like body I of the frame, and the flange l0,spaced from the face of body I, being rigidly integrated in the framestructure, by means of a web portion H. The flange 9 provides aperipheral seat for the window sashes, while the flange l provides aperipheral cleat, with which a plurality of wedge strips (a to g)cooperate in securing the sashes in the frame. The seat flange 9 may,with manifest advantage, be faced with a gasket l2 of felt, or the like.

The window sashes 3, 4, extending edge to edge in common plane, arepositioned in marginal engagement with the seat 9, and the wedge strips(1 to g are anchored between the peripheral cleat l8 and the rims of thesashes, with the effect that the sashes are rigidly secured to the seatin the frame.

Preferably, if not essentially, the bodies of the sashes, each carryinga glass pane G, are formed of metal, and, while the particular way inwhich the metal sash bodies engage and secure the panes is not ofimmediate concern, it is important to note that the rectangular sashbodies are each provided on three sides with outstanding, thin,peripheral flanges l3. When the sashes are assembled in the frame, theyform in effect a single sash having a continuous flange (I3) around itsrim. The flanges l3 are the immediate seat-contacting portions of thesashes; note Figs. II and III; and it will be perceived that the cleatflange I0 is of less lateral extent or breadth than the seat flange 9,in order that the sashes may be readily brought to seated position inthe frame opening 2, or removed from such position.

The wedge strips (a to g) are L-shape in cross section, and, as viewedin Figs. 11 and III, the horizontal web of each strip is greater inbreadth than the vertical web in height. The horizontal web is chiseledged throughout the length of the strip, to facilitate the assembly ofthe strip in the window structure. In assembly the horizontal webs ofthe several strips the webs of the strips that parallel the planes ofthe sashes are wedged in secure position between the peripheral cleatmember ID of the frame I and the peripheral flanges it! of the sashes,with the effect that the sashes are locked in snugly seated position inthe frame. It may be remarked that the vertical webs of the Wedge stripsare accessible to the fingers and tools of the person assembling orremoving the sashes. In Fig. I it will be seen that there is a wedgestrip for each of the sides of the sashes that extend contiguous withthe frame I; the sash 3 is provided with three wedge strips a, b, and c,and each strip extends the entire length of the sash edge with which itis organized. The sash 4 is provided with three wedge strips, e, f, andg, and here I come to a structural refinement of substantial value.Whereas the wedge strips for the lower sash may be identical with thosefor the upper sash, I advantageously provide the Wedge strips for thelower sash in the form of pivoted latch members. That is to say, thewedge strips e, f, and g are pivoted each adjacent to one of its ends(as at I4) to the frame or body of the sash 4, and, as so organized, thewedge strips (collectively considered) are movable substantially in theplane of sash between a position in which the sash is locked in theframe I (Fig. I) and a position in which the sash is freed for removal(Fig. V). It will be noted that the cleat-engaging webs of the strips e,f, and g are cut back (as at [5) adjacent to the pivots l4, with theconsequence and effect that the wedge strips will, when swung into thesash-releasing positions shown in Fig. V, clear the peripheral cleatlfl.

As distinguished from the showing of Fig. I, it will be understood thatboth sashes 3 and 4 may be equipped with the pivoted type of locking orwedging strips, or that both sashes may be provided with detachablestrips like the strips a, b, 0. And needless to say, other modificationsin structure or organization may be made without avoiding the invention.

I claim as my invention:
